Abstract
The invention relates to a numerical control incremental die-less forming method for a thin-walled blade; and the method comprises the following steps of: 1) generating a tool motion track of the thin-walled blade by a processor; using a three-dimensional CAD (Computer Aided Design) modeling to construct a thin-walled blade model; carrying out forming path planning on the thin-walled blade model so as to generate the tool motion track of the thin-walled blade; and setting technical parameters; 2) mechanically machining a supporting cushion block designed in the processor; 3) clamping the supporting cushion block and a plate on a fixture of an incremental forming machine tool workbench; and coating a layer of lubricating oil on the surface of the plate; 4) controlling a forming tool to incrementally form the plate by using an incremental forming machine tool according to the tool motion track generated by the processor and the technical parameters; and 5) after the forming is finished, taking off the thin-walled blade. Compared with the prior art, the numerical control incremental die-less forming method for the thin-walled blade, provided by the invention, has the advantages that the part manufacturing period is reduced, the production cost is reduced, the development of a special mold is not needed and so on.
Description
Technical field
The present invention relates to a kind of method of making thin wall vane, specifically the progressive mouldless shaping method of a kind of numerical control of thin wall vane.
Background technology
Blade is one of most typical part in the machinery manufacturing industry, has in fields such as aviation, automobile, boats and ships widely to use.Therefore, the Design and manufacture level of raising blade is a vital element task.Blade belongs to complex parts more, and is of a great variety, and the free form surface that most of blade profile is had relatively high expectations by geometric accuracy forms.At present, blade fine finishining and semifinishing mainly contain the methods such as Electrolyzed Processing, precision forging and digital control processing.The Nuo Bute Anthony Bu Longsi of General Electric Co. Limited and John's Stewart Reynolds this etc. a kind of equipment (patent No.: 88101230), adopt the accurate blade of making of method of Electrolyzed Processing of Electrolyzed Processing blade proposed; Xu Haoyi etc. propose a kind of finish forge device (patent No.: 89107858.4), realized whole finish forge to large-size steam turbine titanium alloy linear leaf at die hammer of large-size steam turbine titanium alloy linear leaf; Li Kaiyu proposes to adopt the method for numerical control milling to make turbine blade, has improved precision and the quality (patent No.: 200410081331.9) of product.Yet this class thin plate blade of fan blade generally can not adopt said method and adopts traditional sheet stamping forming method to produce more because thickness of slab is thinner.But press-processing method need to be developed special-purpose mould, and the therefore general production cycle is long, cost is also higher, is not suitable for the shaping of small lot blade.
Summary of the invention
Purpose of the present invention is exactly the progressive mouldless shaping method of numerical control that provides a kind of in order to overcome the defective that above-mentioned prior art exists and shorten the part production cycle, reduces production costs, need not develop the thin wall vane of particular manufacturing craft.
Purpose of the present invention can be achieved through the following technical solutions:
The progressive mouldless shaping method of a kind of numerical control of thin wall vane, the method may further comprise the steps:
1) processor generates the movement of tool track of thin wall vane by following steps:
A, the modeling of employing three-dimensional CAD make up the digital model of thin wall vane;
B, form industrial analysis, adding technology replenishes face in digital model, forms the final mask of thin wall vane;
C, according to the lip block of final mask design thin wall vane;
D, final mask is formed path planning, generate the movement of tool track of thin wall vane, and set technological parameter;
2) lip block that designs in the processor is carried out machining;
3) will support backing plate and plate clamping to the anchor clamps of progressive molding platen, and smear one deck lubricating oil in panel surface;
4) the progressive molding lathe carries out progressive molding according to movement of tool track and the process parameter control forming tool that processor generates to plate, and Sheet Metal Processing is become thin wall vane;
5) shaping is complete, takes off thin wall vane.
Described analysis of forming technique is the continuous process complementary surface of concrete shape characteristic Design curved surface according to thin wall vane.
Described process complementary surface comprises assist formation face and clamping face.
The upper surface shape of described lip block is consistent with the upper contoured surface of thin wall vane or bottom profiled face shape.
Compared with prior art, the present invention is applied to this flexible forming method of sheet material progressive molding the production of fan blade.The described progressive molding method of the application of the invention production fan blade does not need to develop special-purpose mould, do not need special forcing press, greatly shortened the many kinds of this class of fan blade, small lot sheet part production cycle, reduced production cost.
